This section contains safety information that must be observed at all times when working on or with the product.
2 Safety SMA Solar Technology AG
Operating ManualSI30M-44M-60H-80H-BE-en-3310

To prevent personal injury and property damage and to ensure long-term operation of the product, read this section
carefully and observe all safety information at all times.
Danger to life from electric shocks due to live voltage and risk of injury from short-circuit currents
High voltages are present inside the SunnyIsland inverter. When the enclosure lid is removed, live components can
be touched that can result in death or serious injury due to electric shock. Short-circuit currents in the battery can
cause heat build-up and electric arcs. Burns or eye injuries due to flashes may result.
• When carrying out any work on the electrical installation, wear suitable personal protective equipment.
• Switch off or disconnect the following components in the following order:
– SunnyIsland
– The control and measurement voltages in the distribution board of the SunnyIsland circuit breakers
– Load-break switch of the battery
• Ensure that the system cannot be reconnected.
• Open the enclosure lid of the SunnyIsland and ensure that no voltage is present.
• Ground and short-circuit the AC conductors outside the SunnyIsland inverter.
• Cover or isolate any adjacent live components.
Danger to life from electric shock due to damaged inverter
Operating a damaged inverter can lead to hazardous situations that can result in death or serious injuries due to
electric shock.
• Only use inverter when it is technically faultless and in an operationally safe state.
• Check the inverter regularly for visible damage.
• Make sure that all external safety equipment is freely accessible at all times.
• Make sure that all safety equipment is in good working order.
Risk of crushing injuries due to moving PV array parts
Moving parts in the PV array can crush or sever body parts. A generator can be started automatically by the
SunnyIsland.
• Operate the generator only with the safety equipment.
• Carry out work on the generator in accordance with the manufacturer's specifications.
Risk of burns due to short-circuit currents on the disconnected SunnyIsland
The capacitors in the DC connection input area store energy. After the battery is isolated from the SunnyIsland,
battery voltage is still temporarily present at the DC connection. A short circuit at the DC terminal can lead to burns
and may damage the SunnyIsland inverter.
• Wait 15minutes before performing any work at the DC terminal or on the DC cables. This allows the capacitors
to discharge.
2 Safety
SMA Solar Technology AG
Operating Manual 11SI30M-44M-60H-80H-BE-en-33

backup system or in a system for increased self-consumption. In a battery-backup system, you can also use the
SunnyIsland for increased self-consumption.

The SunnyIsland supplies AC loads in the system from a battery or charges the battery with the energy provided by
AC sources (e.g., PV inverter). AC sources supply loads and are used by the SunnyIsland to recharge the battery. In
order to be able to increase the availability of the off-grid system and reduce the battery capacity, the SunnyIsland
can use and control a generator as an energy reserve.
The loads may temporarily overload the SunnyIsland. If there is a short circuit, the SunnyIsland briefly feeds short-
circuit currents into the utility grid. As a result, the SunnyIsland may trip certain circuit breakers (for technical data see
installation manual of the SunnyIsland inverter).
Type label
The type label clearly identifies the product. The type label is located on the right-hand side of the enclosure (for a
description of the type label, see the SunnyIsland inverter operating manual).
You will require the information on the type label to use the product safely and when seeking customer support from
Service (see Section16 "Contact", page161).
